ELECTRICAL-CGNDUCTOR CONNECTOR.

Specification of Letters Patent.

Application filed March 25, 1916. Serial No. 86,631.

.To all whom t may concern Be it known that we, HUGH DOUGLAS RoTHwnLn and GORDON Knms, both of the city of Toronto, in the county of York, in theProvince of Ontario, Canada, have in vented certain new and useful Improvements in Electrical-Conductor Connectors, of which the following is the specification. Our invention relate's'to improvements in electrical conductor connectors and the object of the invention is to devise a simple quick means for positively connecting the terminal ends of electrical conductors so as to make a perfect electrical contact between the parts and it consists essentially of the following arrangement and construction of parts as hereinafter more particularly ex plained by the following specification.

Figure 1, is a general perspective view of our connector connecting two terminal ends together. i

Fig. '2, is a longitudinal section throiiigh Fig. 1 and taken on line w-g Fig. 4. Fig. 8, is a longitudinal section taken at right angles to that shown-in Fig. "l, or on line 1 Fig. 4.

Fig. l, is a. cross sectional view on line v i Fig. 2.

Fig. 5, is a cross sectional view showing the parts in closed or gripping position.

Fig. 6, is a perspective detail of the main member of our connector. i Fig. '2', is a perspective detail. view of the gripping jaws removed from the main gripping member.

Fig. 8, is an enlarged sectional fragmentary detail showing a portion of the" outer sleevemember, main gripping memher and movable jaw member co-aoting therewith i In the drawings like letters of reference indicate corresponding parts in each figure.

1 indicates the main member of our connector. Such member comprises the body portion 2 formed nutshaped, a threaded portion 3 and stationary segmental jaw members 4 and 5 extending therefrom so to form an intervening slot (3. '7 indicates an outer sleeve provided with an internal thread 8 at one end designed to engage with the thread oi the main member 1. 9 indicates a series of annular ribs formed on the internal periphery of the sleeve '7' and havi' the top concentric and the base eccenhereto. 10 and llindicate a pair of movanlc jaw members preferably recessed longi tudinally on their inner faces at 12 and 13 to receive the terminal end of the conductor. The outer faces 1% and 15 of each member are curved horizontally and provided with a series of ribs 16 and 17. The ribs 16 are shallow so as to fit into the shallow portion located between the eccentric grooves 9 of the sleeve member I". The rib portions 17 are correspondingly deep so as to fit into the deep portion between the ribs 9 diametrically opposite the portion between which the rooves 16 fit. The members 10 and 11 fit reely into the slot 6 of the member 1 with the rib portions 16 and 17 in engagement with the eccentric ribs 9.

Aswill be noticed upon referring to Fig. 8 the rib portions 1.6 and 17 are slightly sharper in curvature than the interior periphery of the sleeve? and the ribs 9.

In order to hold the jaw members in engagement with the ribs we form longitudinal grooves 18 and 19 in the members 1.0 and 11 into which a li-shaped spring member 20 fits the arms of the Usha-ped spring tending to force the members outwardly into contact with the ribs 21 and indicate terminal ends of an electric conductor. The terminal end 21 is slipped into the longitudinal recesses 12 and 13 when the parts are in the position shown in Fig. 4:. The sleeve member. 9 is then given a half turn thereby carrying the shallow rib portion 16 into contact with the deep portion. of the eccentric ribs 9 so that the base of the groove portions 16 intervening between the ribs 16 bear upon the inner periphery of the annular ribs 9 and so that the rib portions 17 are carried between the shallow portions of the eccentric ribs 9 so that the outer periphery of the portion 17' bears against the base of the grooves located between the rib portions 9. By this operation the jaw member 11 is forced diametrically inwardly against the pressure of the spring '20 SO as to grip Patented Mar. 6, 1917.

lot

the conductor end 21 against the other jaw 10 which has no diametric movement.

We do not describe how the conductor end iis secured as the means and operation are identical to that described in con-- nection with the conductor end 21.

From this description it will be seen that we have devised a very simple device for connecting conductor terminals together winch can be quickly and easily operated and will provide positive connection,

which will form a perfect electrical conbody member having a cylindrical portion slotted diametrically from one end, a sleeve member surrounding such cylindrical portion and in turnable engagement with the body member, a pair of 1;rippi11g jaws freely held within the slot and between which it terminal end is adapted to ext-eml and n plurality of annular ribs formed in the internal periphery of the sleeve with the base thereof eccentric "to the sleeve member and extending ribs formed upon the outer per tions of the jaw members in engagement with the ribs'of the sleeve member but of greater curvature than the ribs of the body. 30
